About our Quadratic Equation Calculator

Quadratic equation Calculator is much useful for students who want to check their answers of a quadratic equation that they have solved. 

How to use our calculator:

  • Enter integer, fraction or decimal which are the coefficients  "x²", x and constant term along with the signs given in the quadratic equation.  .
  • Example: If you have a quadratic equation like 3x²-5x+6, enter the values of A,B and C as A = 3, B = -5 and C = 6
  • If your roots are imaginary, output will be "Imaginary!"
  • If you enter A=0, it is not quadratic equation.

Why do people need this solver?

Apart from the regular calculator, people who study math are in need of quadratic equation-solver. Because, when people work out lengthy problems, they may not have time to solve and find the roots of quadratic equation. At that time, calculating roots of a quadratic equation would be an additional burden for them in solving lengthy math problems. To reduce the burden of those people, we have provided online solver for quadratic equation..

Using the calculator in solving word problems

When people do preparation of solving word problems on quadratic equation, they may have to spend time to get idea on "How to solve". In this situation, they would not like to spend time to do calculation of roots of a quadratic equation. And also they would not be able to use the regular calculators to calculate roots of a quadratic equation. By using this online quadratic equation solver, students will find much time to get idea of solving the word problems.  

Advantages of using this quadratic equation calculator

School students have the topic "solving quadratic equation" in math in their 9th grade or 10th grade. They are given a quadratic equation to solve. They  solve the given quadratic equation but they are not sure whether the answer they got is correct or incorrect. At that time, they can check the answer they have received is correct or incorrect using this solver.  .

Apart from the advantages explained above, this solver can be used as discriminant of the roots of a quadratic equation. That is, to find the nature of the roots of a quadratic equation, this solver can be sued. 

Because, in school, when students study this topic, they are taught a different formula to know the nature of the roots of a quadratic equation. That is Δ = b² - 4ac. Whenever students want to know the nature of the roots of a quadratic equation, they have to compare the given quadratic equation with ax²+bx+c = 0 in order to get the value of "a", "b" and "c". Once they get the value of "a", "b" and "c" , they can plug those values in Δ = b² - 4ac and come to know the nature of the roots.Instead of doing all these works, when our solver is used, answer can be received in a second.
